Programming a Arduino mega 2560

Can someone help me program a Arduino mega 2560 with a proximity sensor so that when a car comes into a garage parking spot, the stop light will either go to yellow or red. I already have the stop light, and the Arduino board.?

Here is a good start for you. You can also google Arduino parking sensor and find several DIY projects that will help you make yours.
